WOOD-SAWING MACHINE.

Specification of Letters Patent.

Patented April 28, ,1908.

Application filed May 25, 1907. Serial No. 875,684.

To all whom it may concern:

Be it known that I, Anon LETROBE Ev- RETT, a citizen of the UnitedStates, residing at North Fort l/Vorth, in the county of Tarrant andState of Texas, have invented a new and useful YVood-Sawing Machine, ofwhich the following is a specification.

This invention relates to machines for sawing and splitting wood and itsobject is to provide simple and efficient mechanism of this characterhaving saws which are independently movable in a vertical direction butwhich are disposed to be simultaneously operated from a common driveshaft.

Another object is to provide means whereby any one of the saws can belocked out of operative position without, however, interfering with theactuation of the remaining saws.

Another object is to provide means for holding the saws against lateralmovement during the cutting operation.

A still further object is to provide simple and efficient means wherebythe wood can be split by the machine during the sawing op eration.

With these and other objects in view the invention consists of certainnovel features of construction and combinations of parts which will behereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a plan View of the machine, a portion ofthe saw guide being broken away; Fig. 2 is a longitudinal section on theline a;-r, Fig. 1; and Fig. 3 is a section on line y-y, Fig. 1 andshowing the upper portion of one of the saw guides in elevation.

Referring to the figures by characters of reference, 1 designates a baseor platform of any preferred construction and extending therefrom nearone end is a supporting frame 2 made up of upstanding strips 3 spacedapart to form slots 4. These strips are connected midway between theirends by a transverse stop strip 5 which is bolted or otherwise securedthereto. Guide strips 6 are arranged longitudinally upon one face ofeach of the strips 3 and have transverse slots 7 designed to receivebolts 8. By fastening these bolts the strips 6 can be adjusted toward oraway from each other to diminish or increase the width of the slots 4.

Standards 9 are mounted upon the base near one end and connecting theupper ends thereof is a bar 10 constituting a pivot for a plurality ofsupporting beams 11. One of these beams extends through each slot 4 andall of the beams are disposed to normally rest upon the stop strip 5.Extending upward from the frame 2 directly above each of the slots 4 isa pin 12 and mounted on each of these pins is a lever 13 having atapered opening 14 therein into which the pin proj ects. One end of thislever is connected by means of a rope 15 or other flexible device withthe beam 11 thereunder while the other end of the lever has a rope orother flexible device 16 secured thereto and hanging downward to a pointwithin convenient reach of the operator. Each of the beams 11 isprovided with a rigid hook 17 near its free end and by pulling down onthe rope 16 the beam 11 can be swung upward so that by swinging lever 13laterally it can be placed in engagement with the hook 17 and supportthe beam in raised position.

Pivotally connected to the free end of each beam 11 is a hanger l8 andanother hanger 19 is pivotally connected to said beam between the bar 10and the frame 2. A plurality of openings 20 is formed within beam 1 1and any one of them is designed to receive a pivot bolt 21 of hanger 19.Both of the hangers are connected between their ends by a brace strip 22there being two sets of openings 23 within the brace strip and anyopening in each set being designed to receive a pivot bolt 24. The lowerends of the hangers are secured in any preferred manner to the endportions of a saw 25. It is of course understood that the strip 22 andthe saw 25 as well as the beam 11 extend through the slot 4 provided forthem. A drive shaft 26 is journaled in the standards 9 and carries aplurality of eccentrics 27. Each eccentric is surrounded by a strap 28connected by means of an arm 29 to one of the strips 22.

A crank 30 is formed at one end of shaft 26 and is connected by a pitman31 with one end of a beam 32. as at 33 upon a standard 34 extendingupward from the base 1. The beam extends through a block 35, the lowerend of which is tapered as shown at 36 and provided with a metallicwedge 37. This -wedge is secured upon the tapered end of the block bymeans of ears 38 which lap opposite faces of the block and are fastenedthereto by means of screws or in any preferred manner. The up per end ofthe block abuts against a reinforce This beam is fulcrumed.

. to be split is designed to be placed.

Supporting strips 41 extend along the base and be ow the saws and journaled within these strips are rollers 42 on which is placed the woodto be cut, and which has been indicated at 43. Holding devices arepivotally connected to one of the strips 41 and consist ofshanks 44having heads 45. Each head consists of a butt designed to be struck by asuitable hammer and a point designed to be driven into the wood so as toprevent it from moving out of proper position while being sawed.

In using the machine herein described all of the saws are raised out ofoperative position by pulling downward on rope 16. Le vers 13 willtherefore pull upward on beams 11. and when the hooks 17 have beenraised to position at one side of the levers 13 said which the holdingdevices are driven thereinto. The saws are then released from the levers13 by pulling said levers out of engagement with hooks 17 whereupon thesaws will drop into position upon the wood 43. When shaft 26 is rotated,as by means of a pulley 46, the eccentrics 27 will reciprocate the strip22 and the hangers 18 and 19 will be oseillated to cause the saws 25 tomove back and forth upon the wood. The weight of the beams 11 and theparts connected thereto will be sufficient to feed the saw into thewood. After the wood has been cut into desired lengths the sections areplaced end-wise upon the block 40. Rotating crank 30 of course actuatesthe beam 32 and causes the splitting device to work upward and downwardand when said device moves downward it will strike the section of woodand split it. It is of course apparent that any one or more of the sawsmay be maintained out of operative position.

It will be seen that the apparatus is very compact and durable inconstruction and is particularly desirable for sawing and splittingkindling wood.

Should any of the beams 11 become worn the guide strips can be adjustedtoward them so. as to prevent lateral movement.

What is claimed is:

1. In a machine of the character described the combination with astandard, a supporting beam pivotally connected thereto, and adjustableguides for the beam; of hangers pivotally connected to the beam, one ofsaid angers being adjustable, a saw carried by the hangers and extendingbetween the guides, a brace strip adjustably and pivotally connected tothe hangers and parallel with the saw and beam, a lifting leverpivotally supported upon the guides, a connection between said lever andthe supporting beam, means upon said beam for engaging the lever tosupport the beam and saw in raised position between the guides, a driveelement, and means for transmitting motion from said element to thebrace strip.

2. In a machine of the character described the combination with guidesadjustable toward or from each other, a supporting beam extendingbetween the guides and pivoted at one end, oscillatory hangers dependingfrom the beam, a saw carried by the hangers, adjustable means forholding the hangers at a desired angle to each other, and means foroscillating the hangers; of an upstanding pivot device carried by theguides, a lifting ever mounted to swing either vertically 01' laterallyupon said device, a connection between one end of the lever and thesupporting beam, and means upon said beam for engaging the lever to holdthe beam and saw in raised position.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.

ARCH LETROBE EVRETT.
